Wind energy two-piece side mounting high-protection busbar side sectional material

Abstract

The invention relates to a wind energy two-piece side mounting high-protection busbar side sectional material. The side sectional material comprises a side sectional material body, wherein the side sectional material body comprises an upper transverse plate, a side plate and a lower transverse plate, wherein the side plate comprises an upper reinforcing rib, a radiating plate and a lower reinforcing rib; a plurality of radiating teeth are arranged on the outer surface of the radiating plate; a first hook plate is arranged at one end of the upper transverse plate; the first hook plate comprises a horizontal plate and a vertical plate; a first mounting groove is formed between the horizontal plate and the vertical plate of the first hook and the upper transverse plate; a second hook plate is arranged at one end of the lower transverse plate; and a second mounting groove is formed between a horizontal plate and a vertical plate of the second hook plate and the lower transverse plate. The side sectional material is simplified in structure and high in rigidity, and has good heat radiation performance; and the side sectional material can be mounted in a wind energy busbar system, so that the busbar protection level is improved.

Description

technical field [0001] The invention relates to a wind energy two-piece side-mounted high-protection busbar side profile, which belongs to the technical field of wind energy transmission and distribution. Background technique [0002] The two-piece side-mounted high-protection busbar system dedicated to wind power generation is widely used in primary transmission sites where the rated insulation voltage of 5MW and below wind power generation is less than 1000v. It mainly carries the primary power output task of wind power generation. It is installed on the inner wall of the wind turbine tower. It is a vertically installed shaft busbar, and it can also be used for horizontal and vertical layouts in civil buildings and general occasions. Due to the narrow and long space of the wind turbine tower, various vertical and horizontal pipelines, complex control systems and transmission equipment passing through the network, the most important thing is that wind farms are usually buil...

Problems solved by technology

[0005] At present, there are mainly three types of wind energy busbar side profiles popular in the market: First, the traditional aluminum-based four-piece low-voltage intensive busbar system, whose side panels are smooth U-shaped profiles, which are simply bent or extruded from aluminum plates. The advantage is that the busbar The structure is simple; the disadvantage is that the rigidity of the U profile is insufficient, the overall busbar is easy to bend and twist, and there is no waterproof design, the protection level cannot meet the requirements of wind energy sandproof and waterproof, and there are potential safety hazards

Second, the traditional aluminum-based four-piece low-pressure air busbar system has corrugated side panels, which are simply rolled out of aluminum panels. The advantage is that it has a certain degree of rigidity and good heat dissipation performance; The connection is unreliable, and there is no waterproof design. The protection level cannot meet the wind energy sandproof and waterproof requirements, and there are potential safety hazards.

Third, the traditional four-piece low-pressure air-type busbar system has side panels made of corrugated steel profiles, which are simply rolled from thin steel plates. The disadvantage is that there is no waterproof design, and the protection level cannot meet the wind energy sandproof and waterproof requirements, and there are potential safety hazards, and the heat dissipation efficiency of the steel side plate is not high, which affects the current carrying of the busbar system
